Essential fatty acids

Essential fatty acids (EFAs) are polyunsaturated fats that aren't made by the body, and it's essential to get them from food. EFAs support and regulate important body functions in the cardiovascular, reproductive, immune, and nervous systems.

The two types of EFAs are:

  • Alpha-linolenic acid. This is found in foods from plants like soybean oil, canola oil, walnuts, and flaxseed.
  • Linoleic acid. This is found mostly in liquid vegetable oils like soybean oil, corn oil, and safflower oil.
